High performance, large aperture medium telephoto macro lens with OS (Optical Stabilizer).
SLD glass provides good control of aberration and the floating inner focus system ensures high rendering throughout the focusing range. By using Sigma's APO Tele Converter, it is possible to take photos at greater than 1:1 magnification. HSM ensures a quiet and high speed AF as well as full-time manual focus override. This lens has a rounded 9 blades diaphragm which creates an attractive blur to the out of focus areas.

Large aperture medium telephoto macro lens

This medium telephoto macro lens allows you to maintain an appropriate distance from subjects while still getting close up photos. Since the working distance at its closest focusing position is 142mm, shadows of the lens and camera will not affect photography making it suitable for taking photos of subjects, such as flowers, under natural lighting conditions. In comparison to the Sigma 50mm and 70mm macro lenses, the main subjects can be defined with perfectly smooth and blurred backgrounds.

Floating inner focusing

This lens incorporates floating inner focusing which moves two lens groups separately. This minimizes aberrations which occur as shooting distance changes, and enables stable rendering of the image from infinity to 1:1 magnification. This also corrects image distortion, especially when taking close-up pictures. Since focusing does not change its overall length, this lens is easy to hold and use.
